This invention relates to furring constructions involving a spacing element andmeans for connecting to the spacing element a member which may or may not itself be furred r from the support.

useful in the constructionof the interior and exterior surfaces of buildings of which the relation in a structure, the spacing elements of the furring devices will admit of the reinforcement foundation being readily secured thereto. Thus, the erector can proceed ex- 2.5 peditiously with the work of securing the reinforcement foundation in place without having had to predetermine the exact positions of said spacing elements.

A further object is to provide a construction in which the spacing element is integral with a metallic structural element, the combination being one form of the furring device.

This application is a continuation of my application, Serial No. 637,537, filed May 8, 1923, as to all matters common to the two applications.

The accompanying drawingsillustrate several forms of the invention. 1

Fig. .7 is a longitudinal view of a third form of locking member.

Describing first the form of the invention. shown in Figs. 1, 1a and 2, and referring more particularlyat present to Fig. 1, the furring device illustrated is especially useful where 1ts supporting structure 1s of masonry construction such, for example, as a cementconcrete wall. One of the members'usedin forming the wall is indicated at 11 and comprises a wooden plank. The furringdevice, indicated ingeneral by the character 12, is driven into said member 11 so as to temporarily support the furring device while the concrete is being poured to form the wall. Only one of the woocen members ll is shown in the drawings as the construction of forms of this character is well understood in the art relating to cement-concrete construction.

The furring device is constructed as follows: The support or shank 13 of the furring deviceis preferably in the form of a screw'blade so as to more firmly secure the furring device against pulling out of the supporting structure 14, shown in Fig. 2. The outer end, of the shank 13 is squared off or, in other words, approximately at a right angle to the longitudinal axis of the shank to form a head which may be struck by a hammer for effecting driving of the furring device into a wooden form member. The projecting furring portion or straight blade or prong 15 of the fur-ring device is preferably such member is employed.

The shank 13 is of a width preferably greater than the width of the blade 15, forming an offset portion at the junction with the blade 15 or, in other words, terminates in a shoulder or shoulders 1'? from which the blade 15 extends and which, contacting with the face of the member 11 when the furring device is driven therein, limits the driving depth of said furring device, thereby predetermining the distance that the furring device projects from the support 1 1. The object of this is to give uniformity to the furring. The shoulders V 17 also function to indicate the depth of setting of the furring' device in the V t mortar joint of a construction built of blocks,

as brick or tile.

The furring portion 15 is provided with an eye or opening 18 designed, when desired. to receive one of the wires 19 of a reticulated member indicated in general by the character 20. In Fig. 2 none of the wires 19 is engaged in the eye 18 but, in order that the wire 19 be placed in the eye 18, a portion 21 of the wall of the eye 18 is partially detached by cutting into the main body of the furring portion 15, so that the portion 21 can be readily removed to produce arelatively wide slot through which the wire 19 can be passed into the eye 18. In the instance illustrated in Fig. 1, the portion 21 is partially detached by providing a kerf 22, extending all the way through the furring portion ,15, and another kerf 23 which extends but part way through the. furring portion 15 Thus, by striking the portion 21, for instance, said portion may be detached to admit the Wire 19. After the wire 19 isplaced in the eye 18, the erector will strike up the tip 16 so as to contract the slot made by the removal of the portion 21, thus to prevent the wire 19 from escaping from the eye 18. However, in Fig. 2, instead of the-wire 19, I have shown a locking member or pin 26 in the eye 18 extending along the outer face of the reticulated member. This locking pin 26 is shown in Fig. 5 and other forms thereof are shown at 26a, 26b, in Figs. 6 and 7 respectively. The locking pin 26, 26a or 265, as the case may be, serves the same purpose as the wire 19 in locking the reticulated member to the furring portion 15.

In order that the member 19 or 26, as the case maybe, may be securely clamped in the eye 18, I prefer to edge, tooth or notch the wall of the eye as indicated at 261 so that, when the eye is contracted, the wall will firmly grip the wire 19 or pin 26.

hen the locking pin 26, 2641 01-265 is employee, the reticulated member 20 may be furred a ;'redeter1nined distance from the support by dropping another of the locking of'the backing 24 and said ins pins into a notch or eye 262 formed in the upper edge of the furring portion 15 or by inserting the same through an eye 263 near the lower edge of the furring portion 15. The spacing of the eye 18 from the notch 262 or eye is substantially equal to the thickness of the reticulated member.

It may be desirable, in some instances, especially when the mesh of the reticulated member 20 is comparatively large, to employ a backing 24 to prevent the cementitious material 25 applied to the reticulated member from falling away from the rear face of said reticulated member. If esired, the backing may be constructed in a manner and of materials that will give to .it the necessary characteristics to make it a thermal or/and sound insulator. l' hen such backing 2 1 is utilized, I prefer to definitely space it tron the supporting structure 14 and, in this in old the back Ag 24 against movement tows. rd Inc-reticulated member 20 during the t on of applying the cementitious 1, are

25 and, accordingly, I provide in the fur-ring portion 15 an eye 28 to receive another of the locking pins 26-, 26a or 26?). The spacing of the notch and eye 28 substantially corresponds to thethickness of the backing 25:.

It may be desiraole, in some instances, employ a sound or/ and thermal insulation alone; the supporting structure 1% rearward .11 may be spaced from the backing to form a dead air space 30. To hold he insulation 29 in place I may employ another of the lockin is 6, 26a or 265 seated in a notch or eye 31 in the upper edge of the furring portion 17,-, or thelockinrg pin may be inserted in an eye 31]. near the lower edge of the blade 15. The eye 311 and notch 31 are spaced tom the supporting structure let a distance substantially equal to the thickness of the insulation 29.

In some instances, the furring device 12, or at least the blade 15, will be coated, as indicated at 3'? in 1a, with suitable resin-- one material or other coating that is both adhesive and yielding to the touch and resistant to chafing and moisture, possessing such insulating qualities as to protect, in some instances, the blade 15 of the furring device 12 and the other metallic members employed in the structure, against metallic contact and frequent consequent oxidation, at points where said blade 15 en ages said other metallic members, and avoid or limit, in some intransmitted by the blade 15 of the furring device 12. The material is preferably applied in two coats, in which instance one coat will be, preferably, soft and one coat Wlll be,

preferably, hard. The object of this is to secure a coating possessing a relative fixedness combining a certain pliableness. I have discovered, therefore, a novelapplication of a coating material especially useful with furring constructions of the type herein described.

In view of my discovery described above, I preferably form my furring device having a support or blade shank for embedding in masonry, of corrosion-resisting metal, since the coating as aforesaid of metallic connecting members such, for example, as, the blade 15 of my furring device, possessing highly corrosive-resistant properties, engaging another or other metallic members such, for eX- ample, as shown in Fig. 2 of the drawings, formed of metals generally used for such members, produces, in addition to'the other qualities possessed by the coating treatment, a practically everlasting structure.

The invention operates as followsL l-ssuming that the member 11 is in place, the erector will drive the furring device into the member 11 until theshoulders 17 .bear against said member as in Fig. 1. The pouring of the concrete in the forms will then be performed as is well understood in the art relating to buildings and other structures, thus embedding the shank 13 of the furring de-.

vice in the concrete structure 14, after which the forms will be removed leaving the furring portion 15 projecting from the wall or, if the supporting structure isconstructed of blocks, during the laying up of the same, the mason will lay the furring device with the shank 13 embedded in one of the mortar joint-s between the blocks, with the shoulders 17 flush with the outer face of said blocks. It may be desirable, in some instances, to provide a dead air space rearward of the backing 24. Then, if in the dead air space 30 an insulation is to be provided, the erector will proceed to place the insulation 29 and lock the same in position by inserting the pin 26 in the eye 31. He will then place a pin 26 in the eye 27 and will place the backing 24' against said pin. He will then lock the backing 24 in place by inserting one of the pins 26 in the eye 28.

The erector will then proceed'to place the reticulated member 2-0 in position, first placing one of the pins 26 inthe eye 262, then positioning the reticulated member against said pin and, finally, placing oneof the pins 26 in the eye 18. He will then strike the tip 16 to close the eye 18 upon the pin in said eye.

The cementitious material will then be applied to the reticulatedmember and forced through the meshthereo'f and against the backing 24, thuscompleting the construction.

N 0W1 referring more particularlyto Figs. 3 and 3a, as illustrating a different form of the furring device, the partsthereofthat correspond in functionto those described above, are indicated by the-same reference characters, with the addition of the letter as In this particular instance instead of the eye 18, the

tip 16Fv is provided with a V-like eye 18, and

the walls of said eye are preferably edged,

notched or toothed, as indicated at 261 The shank 13 is L-shape and is provided with orifices 82 into which the cementitious material passes, so as to aid in'anchoring the furring device'in the support,the flange 83 also aiding in the anchoring.

Now the referring .more particularly to Figs. 4 and 4a, the parts that functionally correspond with those described in connection with Fig. 1 .areindicat'ed by the same reference characters,withthe addition of the letter I). The furring device, in this instance,

comprises a metallic structural member consisting of a support l3 an'd a spacing element or furring portion 15 Thesupport '13 corresponds to the supports indicatedat 13, 13 in the drawings, but it differs from the supports 13, 13 inthat the spacingielement or furring portion 15 is punched therefrom. In the instance illustrated, the support l3 has flanges or walls 3 1 at anangle to each other to form a channel'member, and punched from one of said walls is an ear, blade or prong, thus forming the furring portion 15" and the orifice 36. In this instance, the'furring portion 15 projects at a right angle from one of the walls 3d of the support 13 and extends beyond the plane of said'walL' Itwill be readily understood that part from two adjoining walls of-the support 13 and that it may extend longitudinally of-the'support and, also, that it may be twisted, if desired.

The wall of the eye 18 may be notched or toothed and contracted around any member insertedm said eye by striking against the tip 16", since there is a kerf 22 communicating 165 the furring portion 15 may be punched'in ceiving a locking pin, in the manner describedabovefor the eye 28 and locking pin 26, in-order'to lock in place a backing similar to the backing 24.

Othereyes or notches, if desired, may be providedinuthe furring device 12 to correspend with those described above in connection with Figs. 1, 2 and 3. This will be readily understood without further illustration since it is mere duplication; also, it will be readily understood that it may be desirable,

.in some instances, to provide the locking members securing'the members 20, 24 and 29 in place, continuous from furring device to furring device, in order that the locking members may also firmly engage the members 20, 2d and 29 in place at points between the furring devices, when the turring devices are relatively widely separated.
